Because selection is random and the plume seed is unrevealed until close, anyone cannot dodge the sample, so colluding to grade clones' junk is a canyon gamble with a negative expected value. The lagoon log keeps the sampled set and the penalty so the deterrent is verifiable. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":1,"sig":"WNhCX7StTNQ9bW1ChoZkRERHM37bxQ2fcWpavHGksMHXUQ81HaCH94xansKKNcfjEnkDH8ofXwrYCdzBTUMJexV"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:55:00.946Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
